用jQuery创建的.NET 2.0应用程序老是出错？

Question

我用jQuery创建了一个.NET 2.0应用程序。但是，当我将它部署到没有安装.NET 3.5的服务器上时，它就无法工作。我感觉没有错误，也不知道如何调试它。我使用的是jQuery1.3.2.min.js。此外，在我的测试环境和安装了3.5的另一台服务器上，其工作得非常完美，但是一旦用2.0上传到生产服务器，ASP.NET中的每个回调都会失败。

<script type="text/javascript">
    $(document).ready(function() {
        var item = $("[id$='txtItemName']");
        var category = $("[id$='ddlCategories']");
        var record = $("[id$='txtRecordID']");

        $("#btnSave").click(function() {


            if (item.val().length == 0) {
                alert("Please enter item name first.");
                return false;
            }

            if (category.val().length == 0) {
                alert("Please select a category.");
                return false;
            }

            var paramArray = ["testText", escape(item.val()), "categoryID", category.val(), "recordID", 1];
            PageMethod("SaveMyData", paramArray, AjaxSucceeded, AjaxFailed);

        });
    });

    function AjaxSucceeded (result)   
    {    
        alert("lykkedes" + result);
    }
    function AjaxFailed(result) 
    {
        alert("failed" + result);

    }  

    function PageMethod(fn, paramArray, successFn, errorFn) {
        var pagePath = window.location.pathname;
        //Create list of parameters in the form:   
        //{"paramName1":"paramValue1","paramName2":"paramValue2"}   
        var paramList = '';
        if (paramArray.length > 0) {
            for (var i = 0; i < paramArray.length; i += 2) {
                if (paramList.length > 0) paramList += ',';
                paramList += '"' + paramArray[i] + '":"' + paramArray[i + 1] + '"';
            }
        }
        paramList = '{' + paramList + '}';
        //Call the page method   
        $.ajax({
            type: "POST",
            url: "DataProcessor.aspx?" + fn + "=1",
            contentType: "application/json; charset=utf-8",
            data: paramList,
            dataType: "json",
            success: successFn,
            error: errorFn
        })
    ;} 
</script>

DataProcessor过程如下所示：

public void SaveMyData()
{
    System.IO.StreamReader sr = new System.IO.StreamReader(Request.InputStream);
    string line = "";
    line = sr.ReadToEnd();
    JObject jo = JObject.Parse(line);
    string temp = (string)jo["recordID"];
    Response.Write(temp);
}

我还尝试输入了AjaxFailed（result）......

任何建议都将不甚感激！

The problem may be the JSON serializer, does your server have the ASP.Net 2.0 AJAX Extensions installed?
